Abstract Motivated by the vast gap between photometric and spectroscopic data volumes, there is great potential in using 5D kinematic information to identify study substructures of Milky Way. We Galactic halo 46,575 RR Lyrae stars (RRLs) from Gaia Data Release 3, with metallicities distances newly estimated X.-Y. Li et al. Assuming a Gaussian prior distribution radial velocity, we calculate orbital characterized integrals motion for each RRL, based on its 3D positions, proper motions,...
Abstract The Atacama Large Millimeter/submillimeter Array (ALMA) Survey of Star Formation and Evolution in Massive Protoclusters with Blue Profiles (ASSEMBLE) aims to investigate the process mass assembly its connection high-mass star formation theories protoclusters a dynamic view. We observed 11 massive ( M clump ≳ 10 3 ⊙ ), luminous L bol 4 blue-profile (infall signature) clumps by ALMA resolution ∼2200–5500 au (median value 3500 au) at 350 GHz (870 μ m). identified 248 dense cores,...
Abstract Long and skinny molecular filaments running along Galactic spiral arms are known as “bones,” since they make up the skeleton of Milky Way. However, their origin is still an open question. Here, we compare spectral images HI taken by Five-hundred-meter Aperture Spherical radio Telescope (FAST) with archival CO Herschel dust emission to investigate conversion from H 2 in two typical bones, CFG028.68-0.28 CFG047.06+0.26. Sensitive FAST improved methodology enabled us extract narrow...
The decay ψ(2S) → Ω−+ is analyzed using 14 × 106 events recorded by the Beijing Spectrometer II (BES II) at Electron Positron Collider (BEPC). Based upon with no missing charged tracks and a satisfactory four-constraint kinematic fit, we determine upper limit for branching fraction of to be 1.5 10−4 90% confidence level. By including one track, are able report first evidence an signal statistical significance 3.1σ. determined (4.80±1.56(stat)±1.30(sys)) 10−5.
Long and skinny molecular filaments running along Galactic spiral arms are known as "bones", since they make up the skeleton of Milky Way. However, their origin is still an open question. Here, we compare spectral images HI taken by FAST with archival CO Herschel dust emission to investigate conversion from H$_2$ in two typical bones, CFG028.68-0.28 CFG047.06+0.26. Sensitive improved methodology enabled us extract narrow self-absorption (HINSA) features associated line on off filaments,...
